Answer:
The mass of iodine produced in grams is :
= 476.605 grams of I2
Step-by-step explanation:
Molar mass : It is the mass in gram present in 1 mole of the compound.
The atomic mass of Br = 79.904 g/mol
So , molar mass of Br2 = 2(mass of Br) = 2(79.04) = 159.808 gram
1 mole of Br2 = 159.808 gram
Atomic Mass of I = 126.904 gram
Mass of I2 = 2(mass of I) = 2(126.904)
Mass of I2 = 253.808 gram
1 mole of I2 = 253.808 gram
The balanced reaction is :
According to this reaction ,
1 mole of Br2 will give = 1 mole of I2
159.808 gram of Br2 = 253.808 gram
So , 1 gram of Br2 =
of I2
(Always calculate first for 1 gram by dividing )
300.09 gram of Bromine will produce =
= 476.605 grams of I2
